SoulTale

Monsters' souls are very important to them, it tells them who the love of their life is, who their closest friends are and it is the source of their magic.
Humans' souls cannot do any of these things. They have their own traits, determination, and twinsouls, which are very rare, they're souls that share each others strength.
No, monster in all of existence has ever had a twinsoul, until now. Too bad he's dead.
